Question 61

Regarding the BGP/MPLS IPVPN routing interaction, which of the following descriptions is wrong?

A.The exchange between PE and CE is IPv4 routing information

B.The egress PE can send IPv4 routes to the remote CE through BGP, IGP or static routes

C.The ingress PE converts the IPv4 routes received from the CE into VPNv4 routes and saves them according to different VPN instances

D.After the egress PE receives the VPNv4 route advertised by the ingress PE, it filters the VPNv4 route according to the RT attribute carried by the route

Question 62

As shown in the figure, a sham link is established between PE1 and PE2 through the LoopBack0 interface. CE2 can learn the route of network segment 192.168.1.0/24 (the direct route on CE1) through the sham link and the backdoor link. If the default configuration is maintained, the cost of the route from CE2 to network segment 192.168.1.0/24 should be ( ). (Please fill in the Arabic numerals directly, without symbols)

A.4

Question 63

When there are multiple redundant links in an IS-IS network, multiple equal-cost routes may appear. Which of the following statements is wrong about equal-cost routing within an IS-IS network?

A.If load sharing is configured, the traffic will be evenly distributed to each link

B.A priority can be specified for each route in the equal-cost route, and the route with higher priority will be preferred. the rest as backup routes

C.When the number of equal-cost routes in the network is greater than the number configured by the command, and these routes have the same priority, the route with the larger next-hop device System ID is preferred for load balancing.

D.After the equal-cost route priority is configured, when the IS-IS device forwards the traffic reaching the destination network segment, it will not adopt the load balancing method, but forward the traffic to the next hop with the highest priority

Question 64

After reset isis all is executed, the IS-IS protocol process needs to be restarted, the neighbors need to be re-established, and various IS-IS statistics will not be cleared.

A.TRUE

B.FALSE

Question 65

As shown in the figure, R1, R2, R3, and R4 are in the same MPLS domain, and LDP is used to distribute MPLS labels between devices. R4 is the Egress LSR of the FEC 4.4.4.0/24. If you want to realize that when R1 accesses 4.4.4.0/24, R4 does not need to query the label table but can know the forwarding priority of the data, then the outgoing label of R3 for the FEC should be ( ). (Please fill in the Arabic numerals directly, without symbols)

A.0
